An ectopic pregnancy refers to any gestation implanted outside of the normal intrauterine gestation site. A cesarean scar ectopic pregnancy (CSEP) is the rarest form of all ectopic gestations with CSEPs with an incidence of approximately 1 in 2,000 pregnancies. It refers to the implantation of the gestational sac on a previous cesarean scar and understandably, the incidence of CSEPs has increased lately due to the increase in the number of cesarean sections (CS) performed. It is extremely important to diagnose this condition early as it poses significant morbidity including risks of uterine rupture, rarely, if left undetected. Ultrasound remains an important modality in diagnosing such pregnancies. Here, we discuss three unique cases of scar ectopic pregnancy wherein each has been managed differently.
